Contaminated Site Clean-Up Information (CLU-IN): Internet Seminar Video Archives

Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site. When ICs are jeopardized or fail, direct exposure to human health and the environment can occur...

Optimization activities can improve performance, increase monitoring efficiency, and support contaminated site decisions. Project managers can use geospatial analysis for evaluation of optimization opportunities. Unlike traditional statistical analysis, geospatial methods incorporate the spatial and temporal dependence between nearby data points, which is an important feature of almost all data collected as part of an environmental investigation...

EPA plans to host an informational public webinar to describe key aspects of the financial responsibility formula included in the proposed financial responsibility requirements under CERCLA § 108(b) for classes of facilities in the hardrock mining industry. The comment period will begin after publication of the proposed rule in the Federal Register...

Chemical contaminants in soil and groundwater can volatilize into soil gas and migrate through unsaturated soils of the vadose zone. Vapor intrusion (VI) occurs when these vapors migrate upward into overlying buildings through cracks and gaps in the building floors, foundations, and utility conduits, and contaminate indoor air. If present at sufficiently high concentrations, these vapors may present a threat to the health and safety of building occupants...

Statistical techniques may be used throughout the process of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013, http://www.itrcweb...

Starting on December 31, 2016, exporters of manifested hazardous wastes, spent/used lead-acid batteries, universal wastes and cathode ray tubes for recycling are transitioning from a paper process at the border to an electronic process using the Automated Export System (AES) or AESDirect. This 1-hour webinar will provide detailed filing instructions for exporters and their authorized filing agents (e.g...

When sampling soil at potentially contaminated sites, the goal is collecting representative samples which will lead to quality decisions. Unfortunately traditional soil sampling methods don't always provide the accurate, reproducible, and defensible data needed. Incremental Sampling Methodology (ISM) can help with this soil sampling challenge...

EPA plans to host an informational public webinar to present an overview of the proposed financial responsibility requirements under CERCLA § 108(b) for classes of facilities in the hardrock mining industry. EPA intends to cover the structure of the proposed rule and outline key background documents that accompany the rule. EPA also expects to discuss the public comment process on the proposed rule...
